The nurse receives a prescription for quinidine 20 mg/kg/day to be divided into four equal doses for a client weighing 120 pounds. How many milligrams should the nurse deliver for each dose? Round to the nearest whole number.

Step 1: Convert weight to kilograms Weight (kg) = 120 ÷ 2.2 ≈ 54.55 kg Step 2: Calculate total daily dose Total daily dose (mg/day) = Weight × Dose per kg/day = 54.55 × 20 ≈ 1091 mg/day Step 3: Determine dose per administration The medication is divided into 4 doses/day Dose per administration = Total daily dose ÷ 4 = 1091 ÷ 4 ≈ 272.75 mg Step 4: Round to the nearest whole number ≈ 273 mg per dose Final Answer: 273
